4:6 And because you are children, God sent out the Spirit of his Son into your hearts, crying,

“Abba, Father!”

therefore we are servants no longer to it.

4:7 So you are no longer a bondservant, but a son; and if a son, then an heir of God through Christ.

4:8 However at that time, not knowing God, you were in bondage to those who by nature are not gods.

4:9 But now that you have come to know God, or rather to be known by God, why do you turn back again to the weak and miserable elemental principles, to which you desire to be in bondage all over again?
